Answer

Correct answer: b) Sodium chloride, potassium chloride, trisodium citrate, glucose, water

The WHO standard ORS formula contains sodium chloride, potassium chloride, trisodium citrate (as a buffering agent to correct acidosis), and glucose (to exploit sodium-glucose co-transport for active water/electrolyte absorption even during secretory diarrhea) — not lactose, sodium nitrate, or potassium hydroxide, which are either irrelevant or unsafe substitutions.
